IPC: B23K26/38
Filed: 1994-02-24
Abstract: PURPOSE:To prevent the deterioration of cut surface quality and the generation of erosion in machining at a switching part of machining condition and at a corner part in laser cutting. CONSTITUTION:At a switching part of machining condition, once cut locus is retreated, after machining condition is switched, machining is continued while subjecting to cooling or not. In machining a corner part, after a corner tip part is machined and machining is executed from the tip part with low input machining condition, machining condition is again changed. Right after piercing, cooling is once executed, subsequently, cutting is started. By this method, at a machining condition switching part, erosion is not generated on cutting surface so as to obtain good cut quality with low defect. In machining a corner part, erosion is not generated so as to obtain good cut quality with a low defect incidence. At a switching part from piercing to cutting, erosion is not generated so as to obtain good cut quality with a low defect incidence.

Title: Variable venturi carburetor
Inventor: ITOU TAKAAKI
IPC: F02M19/06
Filed: 1985-02-15
Abstract: PURPOSE:To suck fuel smoothly by employing a linear tube between the float chamber and the variable throttle section of variable Venturi carburetor while atomizing the vapor bubble at the variable throttle. CONSTITUTION:A tapered needle 16 fixed to the end of a laterally slidable suction piston 15 will adjust the throttle area through the gap against the restricting section 13 thus to control the amount of fuel.

Title: Rail excellent in resistance to internal fatigue damage at gage corner
Inventor: KAGEYAMA HIDEAKI
IPC: E01B5/02
Filed: 1990-02-07
Abstract: PURPOSE:To improve resistance to fatigue damage in the inner part at a gage corner by specifying the structure of railhead and the hardness in the part from the gage corner to the position at a specific depth, respectively, in a rail to be laid in the sharp curve section of a railway. CONSTITUTION:This rail has a fine pearlitic structure in a railhead and also has 350-420 Vickers hardness in the part from the gage corner to the position at a depth of 20mm in the inner part. This rail has superior resistance to fatigue damage in the inner part at the gage corner. when the above Vickels hardness is below 350, a highly work-hardened layer is formed at the surface layer at the gage corner and internal fatigue damage is developed in its vicinity. Further, the reason why the upper limit of Vickers hardness is regulated to 420 is that this value is the upper limit of the hardness which can be obtained in the fine pearlitic structure, and, when a hardness exceeding the above upper limit is desired, a harmful structure, such as martensitic structure, is mixed into the structure.

Title: Method for electronically controlling fuel injection in internal-combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/18
Filed: 1982-02-23
Abstract: PURPOSE:To enable the amount of fuel to be injected to be increased properly acceleration according to the warmed condition of the engine in a fuel injection device wherein a basic amount of fuel injection in compensated in accordance with the oprating condition of the engine by a method wherein when, during acceleration, a compensating factor is increased and then attenuated the attenuating speed is changed over according to the warmed condition of the engine. CONSTITUTION:In case a control circuit 54 receives an air intake pipe pressure signal transmitted by an air intake pipe pressure sensor 23 and a signal indicative of the number of revolutions of the engine transmitted by a crank angle sensor 44 to find a basic amount of fuel injectin to control a fuel injection value 30, during the acceleration, the amount of fuel injection is increased by an after-idling which enables a rapid compensation for increase in the amount of fuel to be injected to be made. This increase in the amount of fuel is made by setting first the compensating factor at a positive predetermined value and then attenuating the factor to zero at a predetermined attenuating speed every engine revolution or every predetermined time. In this case, when the warming-up of the engine has proceeded and the attenuating speed has reached a predetermined level which varies according to a cooling water temperature signal transmitted by a cooling water tempeature sensor 46, the attenuating speed is changed over to a speed which is comparatively low as compared with that which has been kept.

Title: Electronic flash device
Inventor: YAMADA MASANORI
IPC: G03B15/05
Filed: 1984-02-15
Abstract: PURPOSE:To eliminate the breakage of a control circuit element caused by lack of apply of high voltage and to improve the use efficiency of a battery by using the output of a boosting circuit as the operating voltage of a control circuit only when the feed terminal voltage of the control circuit drops abnormally. CONSTITUTION:When a flash discharge tube 14 for preliminary light emission turns on, the output voltage of the battery 2 drops abruptly and the voltage VCC at the feed terminal of the control circuit 77 also drops. When the voltage determined by voltage-dividing resistances 67 and 68 drops below the voltage of a Zener diode 70, the output of a comparator 71 is inverted to a high level and transistors (Tr)73 and 9 turn on to supply the charge of a capacitor 8 to the feed terminal of the circuit 77, so that the voltage VCC rises. The output of the comparator 71, on the other hand, is inverted to a low level by the rising of the voltage VCC and the Trs 73 and 9 turn off. The voltage VCC is therefore stabilized to the Zener voltage of the diode 70 and the circuit 77 operates normally.
